In this part, a method will be introduced to restore your iphone without i Tunes.
Back up your i Phone data This step is of great importance. But if you don't want to lose any significant data file on your i Phone, such as contacts, text messages, photos, videos and so on, we suggest you'd better back up i Phone data first.
When you find the delay time is longer when you launch Camera, Contacts, or other applications, you may need to restore the device.
For many cases like the situations mentioned above, numbers of i Phone users are unwilling to upgrade their devices when they have to restore their i Phone 4/5/6/7.
Choose the backup you've made and wait for the completion of the restoration.
More and more data storage will take up much space of your i Phone, such as photos, videos, text messages, etc.
To begin with, install and launch the full-featured software. Connect your i Phone with PC or Mac via a USB cable, and then the program will automatically detect your device.
It will show main information of the device type, size, and more. From the mode of "Recover from i OS device", click "Start scan" button.
This will erase everything off you device and return it to the factory settings.
This is a useful tool if you have made a mistake on jail breaking or for whatever reason you might have.
